Abstract
The utility model discloses a kind of novel deflecting bit, comprises joint pin and bit body, it is characterized in that: on described bit body, center is symmetrically arranged with some twisted shape wings, wing is provided with some cutting elements; Described bit body is provided with some hole for water sprayings between wing.Described bit body and wing are all made up of carcass.The wing of bit body of the present utility model and twisted shape by carcass Integral design, and arranges cutting element respectively on wing, has good guidance quality, improves deflecting efficiency, and then reduces drilling cost.
Description
Technical field
The utility model belongs to oil bit field, specifically, relates to a kind of novel deflecting bit.
Background technology
At present in oil exploration & development, Technology of Directional Drilling obtains and develops rapidly, and deflecting bit is the important tool of directional drilling fractured rock.But because the contact area of existing deflecting bit and bottom is little, during bit operation, jumping frequency rate is high, causes drilling tool job insecurity, be difficult to the directional drilling ensureing drill bit, therefore, cause build angle rate low, service time is short, causes drilling well deflecting to have deviation, improves the cost of probing.
Utility model content
For solving the problem in background technology, the utility model provide a kind of reasonable in design, to have contact area large, good stability, improves the high effect of deflecting efficiency, and then reduces the novel deflecting bit of drilling cost.
The technical solution of the utility model is:
A kind of novel deflecting bit, comprises joint pin and bit body, it is characterized in that: on described bit body, center is symmetrically arranged with some twisted shape wings, wing is provided with some cutting elements; Described bit body is provided with some hole for water sprayings between wing, and the centre position, upper end of bit body is provided with circular jetting water hole; Described bit body and wing are all made up of carcass.
As a kind of technical scheme of optimization, the number of described wing is N number of, and wing is separately installed with cutting element.
As a kind of technical scheme of optimization, between described wing, the number of hole for water spraying is N number of, wherein has 1 ~ 2 nozzle between every two wings.
As a kind of technical scheme of optimization, described bit body and wing are integrated design, and composite sheet or impregnated tooth are embedded on wing.
Owing to have employed technique scheme, compared with prior art, the wing of bit body of the present utility model and twisted shape is by carcass Integral design, and on wing, cutting element is set respectively, there is good guidance quality, improve deflecting efficiency, and then reduce drilling cost.
Accompanying drawing explanation
Fig. 1 is the structural representation overlooked of a kind of embodiment of the utility model.
Detailed description of the invention
Embodiment
As shown in Figure 1, a kind of novel deflecting bit, comprises joint pin and bit body 1, and on described bit body 1, center is symmetrically arranged with some twisted shape wings 2, and wing 2 is provided with some cutting elements.Described bit body 1 is provided with some hole for water sprayings 3 between wing.Described bit body 1 and wing 2 are all made up of carcass.
In the present embodiment, the number of described wing 2 is N number of, wing 2 is separately installed with some composite sheet or some impregnated tooths.
Between described wing 2, the number of hole for water spraying 3 is N number of, has 1 ~ 2 nozzle between every two wings.
In addition, consider actual needs, described bit body 1 and wing 2 are integrated design, and composite sheet or impregnated tooth are embedded on wing.
The wing of bit body of the present utility model and twisted shape by carcass Integral design, and arranges cutting element respectively on wing, has good guidance quality, improves deflecting efficiency, and then reduces drilling cost.
The utility model is not limited to above-mentioned preferred embodiment, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or akin technical scheme with the utility model, all belongs to protection domain of the present utility model.
